FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Fault tolerant CAN transceiver extended modes
By setting CEXT to 1 the transceiver cell supports sub bus communication
Note: if DFIS bit is set to 1, WUR register must be read before going into sleep or stop mode in order to clear the wake-up flag.
During read out L0 must be at high level and should stay high when entering sleep or stop.
Comments:
CS2 bit at 0 = open failure. CS2 bit at 1 = short failure.
(CS3 bit at 0 and (CS1 = 1 or CS2 =1)) = CANH failure. CS3 bit at 1 = CANL failure.
CS1 and CS0 bits: short type failure coding (GND, VDD or VBAT).
In case of multiple failures, the last failure is reported.
.
Notes
34.
CEXT Bit should be set at 0. The CAN operation in extended mode is not recommended.
FDIS
L0 Wake Input Filter (20
s Typical)
0
Enable (LO wake threshold selectable by WUR register)
1
Disable (L0 wake-up threshold is low level only, no matter D0 and D1 bits set in WUR register).
